How we handle glazing silicone in Harrowcross
Sealant on glazing doesn’t last for ever. Sun, rain and movement wear it down and cracked joints let water in. Renewing it keeps glazing joints doing their job. We are often asked to deal with failed joints on frameless glass and silicone pulling away from the glass, across glass-to-glass joints, rooflights and glass-to-frame joints.
Somewhere as small as Harrowcross, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
All our work is covered by our 12-month guarantee.

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Check the gutters above the glazing for debris
- Look over the glazing joints once a year
- Get a new leak looked at quickly
- Run a squeegee over the glass when you’re done
Clear the conservatory gutters regularly, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.
A small conservatory leak soon spreads. Water runs along frames and down walls so it’s best dealt with straight away.
What we are called out for in Harrowcross
Sunlight breaks sealant down and roof joints get the most sun. It goes brittle, cracks and stops sticking to the glass and frame.
Most people get in touch when they notice something like this:
- Drips on the inside of a conservatory window
- Silicone pulling away from the glass
- Conservatory leaks at frame and glazing joints
- A quick top-up bead that didn’t last
Homes close to Church of St Peter include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Surface by surface
Shower screens
A screen’s wall joint and tray joint are where leaks start. We reseal both with anti-fungal silicone.
Glass-to-glass joints
You see these joints clearly, so a straight, even finish matters.
Why act early in Harrowcross
Fixing a leaking screen early protects what’s underneath. Water from a failed joint can soak into the floor before it shows. Around Harrowcross, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.

Windows and doors in Harrowcross
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Hedingham Castle (about 1.7 miles north-east) nearby, there’s older building stock in the area around Harrowcross as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Managing a site like Hedingham School and Sixth Form? Then its window and door frames need their mastic kept sound, just like a home’s.

The process
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and clear up. Most jobs take a few hours, depending on how many joints need doing. For a village or hamlet like Harrowcross, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by finding the leak and making sure sealant is the cause.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
How to prepare
- Keep children and pets away from the work area
- Clear items away from the joints we are working on
- Let us know if you’ve seen damp or leaks

Harrowcross: your questions answered
Is there a guarantee on glazing silicone in Harrowcross?
All our work, in Harrowcross and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Is Harrowcross within the area you cover?
Yes, Harrowcross is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you seal glass balustrade bases?
We can, if the base joint is sealed. Send us photos and we’ll take a look when you ring 0345 464 0079 or send us an email.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you don’t need to watch us work.
How long does the job take?
Typically it takes anything from an hour or two to most of a day, depending on the size of the job. Larger jobs naturally take longer, and we’ll tell you how long to expect.
Is it enough to run a bead over the old sealant?
It doesn’t last. Fresh silicone will not bond to cured silicone so we take it all out and start clean.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Which silicone is used for glass joints?
A neutral-cure glazing silicone suited to glass and the frame. Shower screens get anti-fungal silicone.
